Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446996, here are decompositions:

13 + 31446983 = 31446996
23 + 31446973 = 31446996
43 + 31446953 = 31446996
47 + 31446949 = 31446996
59 + 31446937 = 31446996
79 + 31446917 = 31446996
103 + 31446893 = 31446996
137 + 31446859 = 31446996

Showing the first eight; more decompositions exist.
